Is Britain gearing up for another royal wedding — and a new princess? Almost two decades after the nuptials of his late mother, Princess Diana, and father, Prince Charles, transfixed the nation, Prince William is said to be planning to propose to longtime girlfriend Kate Middleton. An insider tells People magazine that an engagement is “a given. It’s just a question of when.”

Oddsmakers are offering 1-to-2 chances that a proposal will happen soon. “We’ve seen quite a bit of money, suggesting an engagement is imminent,” a betting-house rep said.
